Here is a SQL script to do I/O performance test with INSERT statement using BIGINT with PRIMARY KEY.

DECLARE @Count INT
SET @Count = 100
DECLARE @Size INT
SET @Size = 256

DECLARE @STime DATETIME
DECLARE @ETime DATETIME
DECLARE @Duration INT

DECLARE @I INT
DECLARE @Message VARCHAR(5760)
SET @Message = 'The quick brown fox jumps over the lazy dog. '
SET @I = 7
WHILE @I > 0 BEGIN
   SET @Message = @Message+@Message
   SET @I = @I - 1
END
SET @Message = SUBSTRING(@Message,1,(@Size-8)/8-2)

CREATE TABLE TEMP_DATA (
   ID BIGINT,
   MSG_1 VARCHAR(4096),
   MSG_2 VARCHAR(4096), 
   MSG_3 VARCHAR(4096), 
   MSG_4 VARCHAR(4096), 
   MSG_5 VARCHAR(4096), 
   MSG_6 VARCHAR(4096), 
   MSG_7 VARCHAR(4096),

) 

select t.name, p.partition_id, p.rows, a.type_desc, 
   a.data_space_id, a.data_pages, f.file_id
   into #TEMP_STATS
   from sys.objects t, sys.partitions p, sys.allocation_units a, 
      sys.database_files f
   where t.name = 'FYI_DATA'
      and t.object_id = p.object_id 
      and p.hobt_id = a.container_id
      and a.data_space_id = f.data_space_id

SET @STime = GETDATE()
SET @I = 1
WHILE @I <= @Count BEGIN
   INSERT INTO TEMP_DATA VALUES (@I,@Message,@Message,@Message,@Message,
      @Message,@Message,@Message,@Message)
   SET @I = @I+1
END
SET @ETime = GETDATE()

SET @Duration = DATEDIFF(millisecond,@STime,@ETime)
SELECT @Size AS Size, @Count AS Count, @Duration AS Duration, 
   ''''+CONVERT(VARCHAR,p.partition_id) AS Partition, p.rows-l.rows AS '+Rows', 
   a.type_desc AS Allocation, a.data_pages-l.data_pages AS "+Pages", f.file_id
   from sys.objects t, sys.partitions p, sys.allocation_units a, 
      sys.database_files f, #TEMP_STATS l 
   where t.name = 'FYI_DATA'
      and t.object_id = p.object_id 
      and p.hobt_id = a.container_id
      and a.data_space_id = f.data_space_id
      and l.file_id = f.file_id
      and l.partition_id = p.partition_id
      and l.type_desc = a.type_desc

DROP TABLE #TEMP_STATS
DROP TABLE FYI_DATA

This script uses a temporary table to keep a copy of different counters of about the target table before the test.

New values of those same counters are compared with old values to calculate the changes.

Run the script with the default @Size and @Count values on SQL Server. The output shows that the script is working correctly:

SIZE  COUNT  DURATION  PARTITION           +ROWS  ALLOCATION         +PAGES  FILE_ID
256   100    63        '72057601516896256  100    IN_ROW_DATA        4       1
256   100    63        '72057601516896256  100    ROW_OVERFLOW_DATA  0       1
